Equilibrium and Balance

Equilibrium and Balance

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Increased Intracranial Pressure ll: Pathophysiology

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...

Major Somatic Sensory Pathways

Major Somatic Sensory Pathways

Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...

Gyroscope: Precession

Gyroscope: Precession

Precession can be demonstrated effectively through a spinning top. If a spinning top is placed on a flat surface near the surface of the Earth at a vertical angle and is not spinning, it will fall over due to the force of gravity producing a torque acting on its center of mass. However, if the top is spinning on its axis, it precesses about the vertical direction, rather than topple over due to this torque. Precessional motion is a combination of a steady circular motion of the axis and the...

The Vestibular System

The Vestibular System

The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Increased Intracranial Pressure l: Introduction

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...

Summary

This summary is machine-generated.

Rotational vertigo can stem from small brain lesions in the supratentorial subcortical region. This case highlights a potential link between specific infarct locations and vertigo symptoms.

Neurology
Neuroimaging
Neuroscience

Background:

Cerebrovascular events, such as ischemic stroke, can manifest with diverse neurological deficits.
Rotational vertigo is typically associated with vestibular system disorders, often originating in the brainstem or cerebellum.

Observation:

A 57-year-old male presented with left hemiparesis and was diagnosed with a right putamen to corona radiata infarct via magnetic resonance imaging (MRI).
The patient developed rotational vertigo three hours post-symptom onset.
Truncal ataxia was observed days later, persisting into the chronic phase, with no new lesions detected on follow-up MRI.

Findings:

The infarct was localized to a small, supratentorial, subcortical area.
The clinical presentation included hemiparesis, rotational vertigo, and persistent truncal ataxia.

Implications:

This case suggests that small, supratentorial, subcortical infarcts can be an underrecognized cause of rotational vertigo.
Neuroimaging findings correlated with specific neurological symptoms, aiding in differential diagnosis.
Understanding the neuroanatomical basis of vertigo symptoms is crucial for accurate diagnosis and treatment of stroke patients.
